Best Answer

Excessive moisture and rainy or humid weather can lead to this problem known as leaf spot. Always remove old dead leaves, and cut off and destroy any leaf or part of a leaf that is affected. In the spring, about six weeks before bloom, begin a regular spraying program with a fungicide.
